Multi element security system

Abstract

A security system is provided for a mobile piece of equipment such as a freight car, aircraft, boat, automotive/truck vehicle, or other machine that may be stolen. The system consists of a central processing unit, transporting a stream of data to various components of the vehicle, and component control units attached to each of the parts of the vehicle being protected. The control units accept a code from the memory of the vehicle ignition key, alter the code, and transmit the altered code back to the CPU. The operation of certain devices that effect the operation of the vehicle and/or its protected subsystems are also disabled. These systems in turn may be linked to a central database via a system control center to control the inventory and regulation of parts both within each vehicle and between all vehicles protected by the system.
